Be it known that I, AUGUsTUs BURCKARD, a citizen voft the United States, residing at Baltimore, in the State of Maryland, have in'- vented certain new and useful Improvements in Carpet-Cleaning Machines; and I do declare the following to bea full, clear, and exact descripti'on of the invention,'such as will enable others skilled in the art towhichit appertains to make and use the same, reference being hadl to the accompanying drawings, and to they letters and gures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in carpet-cleaning machinery, wherein provision is made to thoroughly free the carpet of ,dust

, bya sufficiently violent but safeimpact simultaneously applied onboth sides ofthe carpet,

the mechanism to produce this result being so constructed that this force of impact is'im-` parted to the carpet through a yielding medium which eliminates all dangenof injury to the carpetcand at-the same time'per'mits sufficient force to be applied to drive out all particles of dust which maybe held between the threads, additional` provision being made in the construction of thesaid mechanism to permit a freeescape of the particles of dust as they arel driven from the texture. lFurther provision is made by the employment of a suitable deviceto continuously feed the carpet through'the machine, and a revolving 'brush provided to impart a'nishing cleansing-to the carpet after .it has left thebeater, the entire operation being performed automatically by vthe device which may be operated by either steam or other power.

In the further vdescription of my invention, reference is had to the accompanying drawings, in whichl p Figurel is a side elevation of the device with a portion yof vone side frame removed, showing section-through the cross-head, bed, and beater.` Fig. 2 is a view looking down upon the devicewith a portion of the carpet removed. l t v t rlhe same figures refer to the same'or similar parts thoughout the severalv views.

The figure 4 denotes the foundationstring-v ers upon which the device is mounted, the side frames, 5, kbeing supported thereon by the legs cape of dust as it `is beaten from the under sideof thel carpet.` kThe up'rights 7, which con?, i i y stitute a part ofthe frame are strengthened by' 6V at asufficient Vheight to permit the4 free es#` the braces '8 andform' a support on the top vthereof for the rotating shaft 9, proper journals,9%, being provided thereonfor. thisjpur# n pose. f s

In the rectangular space Which/is formed bythe side frames, 5, and the end frames, 10,

and free to vibrate thereinis placedthe yield# i-ng'bed 11, which is of rectangular form land made of fairly stout wire-netting, 1 2,itsp`eripl`1-y erybeing formed of stout Wire 13, to which is.

65. vsecured the fsaid Wire-netting 12. This bed 11 is supported in position upon `the springs t 14, lfour ofxthem being represented inthe drawings, one placed atfeachjcorner, suitable j supports being provided therefor by the pieces 15,vvhich` are secured to the frames 5 and 10.

Any number of these springs may be employed,

however, and proper supports provided by the said frames. j p .y

v The shaft 9,-which issupported ontop of the nprights 7, is caused to rotate by means ofthe driving-pulley 16, which may bedriven jby steam orfother power. This shaft 91s yprovided with two or moreicranks, 17which are t Aplaced in line for coincidental movement on the said shaft 9, and are connected bythe conmeeting-rods 18 to the cross-head 19, wherebyv a vertical reciprocatingfmotion is imparted thereto, proper guides, 20, being' formedin vthe uprights 7, in which the ends of thesaid cross-head 19 moves. Suspended underthe said lcross-head 19 by means of the springs 21, and thereby caused to move in unison therewith, is the beater 22, which is'of rectangular form and of like construction of the bed -11, its periphery being formed of the stout Wire, 23, to which is secured "the wire-nettingY 24..- The springs 21 whichv support this beater are placed as representedin the drawings, Fig. 2, two of them being secureddirectly to the bottom of the cross-head 19, and thetwo others are supported by the arms 25, which are secured l to the said cross-head 19' for this purpose;

At one end of the device is placed aroller,

26, which has its bearing in some part `0f the frame,- 'and serves to roll the carpet upon pre-` 1 lparat'oryitc cleaning, a crank, 27 ,being placed on the projecting spindle thereof for convenience of rolling the carpet thereon. At the other end of the device is similarly placed a like roller, 28, which is caused to rotate by some moving part of the machine. As represented in the drawings, a ratchet-wheel, 29, is provided on the projecting spindle of the roller 28, which is operated in the usual manner by a pawl, 30,which is placed on one end of the vibrating lever 31, the said vibrating lever 31 being fulcrumed at 32, and receives its motion through the eccentric-rod 34 from the eccentric 33, which is secured tothe shaft 9, whereby when the shaft 9 is caused to rotate a feeding movement will be imparted to the roller 28, and the carpet 35,which has its free end secured thereto, will be drawn ofi' the roller 26 and wound on the roller 28, the small rollers 36 being provided and placed in proper positions between the said rollers 26 and 28 to lessen the friction and properly stretch the carpet 35 between the bed 11 and the beater 22 as it moves from the one roller to the other.

l end thereof,which is driven bya belt, 40, from alike pulley, 39, secured to the shaft 9, the bristles of the said brush 37 being placed in clusters 41, as represented in Fig. 2.

The manner of operating is as follows: The machine may be constructed to accommodate any width of carpet, which is first wound upon the roller 26, the crank 27 serving to aid in thisoperation. Vhenthecarpet35isall upon the roller 26, its free end is passed over the roller 36, between the beater 22 and the bed 11, after which it is passed under the brush 37, over the roller 36 at this end, and then secured to the feed-roller 28. The driving-pulleyV 16 is now thrown in gear and the shaft 9 caused to rotate, the cranks 17 imparting a vertical reciprocating movement to the crosshead 19 and beater 22in the manner described. The vertical movement of the cross head 19 is so adjusted that the beater 22 will strike the bed 1l with the desired force, the springs 14 of the bed and the springs 21 of the beater yielding sufficiently to the impact to prevent injury to the carpet, at the same time giving sutlicient shock, and the vibrations of the bed 11 and beater 22 causing suilcient shaking to dislodge any particles of dust which may be held in the threads of the texture, and thus imparting alike shock on both sides of the carpet insures a cQmplete dislodgment of the dust throughout, the dust escaping through the meshes of the net 12 in the bed 11, and from thence to the floor, or a draft of air or other provision might be made to dispose of them. In like manner the meshes of the net 24, which forms the beater 22, permit the dust to escape from the upper surface and may be disposed of by an air-current or other means. The roller 28, which was caused to rotate when the driving-pu1ley 16 was thrown in gear in the manner described, causes a gradual passage of the carpet 35 through the device,rst subjecting it to the action of the beater 22, and from thence carrying it under the revolving brush 37, which removes any particles of dust which maybe remaining on the surface thereof, the rollers 36 serving to lessen the friction and maintain a proper position of the carpet 35 as it passes through the machine. The operation is continued `until all the carpet has been Wound upon the roller 28, when the roller may be removed and the roll of carpet taken therefrom.

Having described my. invention and the manner of operation, what I claim, and desire to secure by United States Letters Patent, is-

1. In a carpet-cleaning machine, thecombination of the bed 11, the rotating shaft 9, the cranks 17, the connecting-rods 18, the crosshead 19, the guides 20, thc beater 22, constructed of wirenetting and secured to the cross-head 19, and mechanism to feed the carpet between the said beater 22 and bed 11, consisting ofthe eccentric 33, eccentric-rod 34, lever 31, pawl 30, ratchet-wheel 29, and roller 28, for the purpose set forth.

2. In a carpet-cleaning machine, the combination of the bed 11, the rotating shaft 9, the cranks 17, the connecting-rods 18, the crosshead 19,the guides 20, the beater 22,constructed of wire-netting, the springs 21, by which the AUGUSTUS BURCKARD.-
